The related art described above discloses wheeled toys that present imaginative characterizations including prominent head structures. However, the prior art fails to disclose a three-wheeled toy and particularly one with a simplified carriage structure adaptable for use in a forward single wheel adaptation as well as a rearward single wheel adaptation. The present disclosure distinguishes over the prior art providing heretofore unknown advantages as described in the following summary.

BRIEF SUMMARY OF THE INVENTION

This disclosure teaches certain benefits in construction and use which give rise to the objectives described below.

A mechanized toy includes a carriage supported on three wheels with a decorative cover engaged with, and extensive over, the carriage. The carriage provides a simplified structure having a platform integral with an axially directed yolk, the yolk engaging one of the three wheels. A drive motor is secured below the platform and rotates a drive axle that is therefore low to the ground and engages the other two of the three wheels which are placed in mutually opposing juxtaposition with respect to the platform. The two wheels are driven by the drive motor and yet are able to be quite small due to the low deployment of the drive axle. In this way, the one wheel may be quite large and visually dominant. A snap engagement feature enables the cover to be attached to the carriage and to be removed from the carriage as desired. When several different covers are used with a single carriage, the covers may be interchanged and the single wheel may be leading or trailing depending on the configuration of the selected cover so that the toy may be converted from the appearance of a dragster, for instance, to that of a face-forward character.

A primary objective inherent in the above described apparatus and method of use is to provide advantages not taught by the prior art.

Another objective is to provide a mechanized rolling toy with simple construction and operation.

A further objective is to provide such a toy with fanciful characterization.

A still further objective is to provide such a toy with mechanically interchangeable covers so as to change the appearance and nature of the toy.

A still further objective is to provide such a toy with three wheels wherein, depending on the cover selected, the toy may be configured with a single wheel in a leading or in a trailing position.

Other features and advantages of the present invention will become apparent from the following more detailed description, taken in conjunction with the accompanying drawings, which illustrate, by way of example, the principles of the presently described apparatus and method of its use.

DETAILED DESCRIPTION OF THE INVENTION

The above described drawing figures illustrate the described apparatus and its method of use in at least one of its preferred, best mode embodiment, which is further defined in detail in the following description. Those having ordinary skill in the art may be able to make alterations and modifications what is described herein without departing from its spirit and scope. Therefore, it must be understood that what is illustrated is set forth only for the purposes of example and that it should not be taken as a limitation in the scope of the present apparatus and method of use.

Described now in detail, as shown in the attending figures and particularly FIGS. 6 and 7, is a mechanized toy 10 having a carriage 20 supported on three wheels 31, 32, 33 and a decorative cover 40 engaged with, and extensive over, the carriage 20, the cover providing a design or characterization of the toy 10. The carriage 20 is constructed as a horizontal platform 22 integral with an axially directed yolk 24, and the yolk 24 engages a first one 31 of the three wheels at axle 25, i.e., the yolk 24 extends to both sides of the wheel 31 as shown in FIG. 3. Wheel 31 is free to rotate within the yolk 24 and is positioned to support the yolk above a supporting surface 5. A drive motor 50 is secured below the platform 22 preferably by screw fasteners or other common fastening means such as bonding agents (not shown), thereby positioning a drive axle adjacent a supporting surface for enabling wheels 32 and 33 to be small in diameter so as to be visually unobvious. Preferably, the carriage 20 and the cover 40 are plastic injection molded parts, but they may be made of alternative materials such as plaster, wood, and paper, and by other then a molding process, as by pressure forming, sculpting, etc.

As shown in FIGS. 6 and 7, the drive motor 50 rotates a drive axle 52 engaging the second 32 and third 33 of the wheels. In the preferred embodiment the two wheels 32 and 33 are place in mutually opposing positions on either side of both the drive motor 50 and the platform 22. Preferably, the drive motor 50 is any one of the common motors used in toys and especially for toy cars. Such motor types include friction motors, spring motors, pull-string motors, and rubber band motors.

A means for engaging the cover 40 with the carriage 20 is preferably one or more snap engagement fasteners 45 shown in FIGS. 6 and 7, and the manner of positioning the fasteners 45 as shown in arbitrary, as such many be positioned as best or necessary for improved support of the cover 40 on the carriage 20. Such snap engagement fasteners 45 each comprise a recess 60 on, for instance, the interior surface 42 of the cover 40 and a correspondingly positioned extension 62 on, and extending upwardly from the carriage 20. Of course, the positions of the recess 60 and the extension 62 may be reversed. Also, plural fasteners 45 may be utilized to better secure the cover 40 with the carriage 20. Because, in this embodiment, the cover 40 is able to be easily removed from the carriage 20, the cover 40, as for instance as shown in FIG. 1, may be replaced with an alternate cover 40, as for instance as shown in FIG. 4 having a different design. Further, the ability to simply remove the cover 40 from the carriage 20 gives children alternative methods of play with the toy 10, such as building an alternate cover on the carriage 20 with modeling clay or other construction materials, and also using the cover 40 with other toys such as toy cars, action figures, and such.

Of course the cover 40 may be permanently engaged with the carriage 20, as for instance by using a bonding agent in the recess 60 prior to engaging the extensions 62 therein. In this case, the toy 10 is manufactured, sold and used as an integral unit and without parts interchangeability.

The present invention may be construed in at least two embodiments; one where the yolk 24 and the one of the three wheels 31 is directed rearwardly relative to the drive motor 50 and the two of the three wheels 32 and 33, as shown in FIG. 6, and the other where the yolk 24 and the wheel 31 is directed forwardly relative to the drive motor 50 and the two of the three wheels 32 and 33, as shown in FIG. 7. In both cases, wheels 32 and 33 drive the toy 10.

Preferably, the cover 40 is formed to resemble the head of a warrior, a person, an animal, a fictional character or other imaginative figure, and more particularly may be formed to resemble a famous person or well-known fictional character from books, films or television. In one embodiment the one of the three wheels 31 is preferably positioned within the head formation portion of the cover 40 and preferably adjacent to, i.e., immediately behind a mouth feature of the head formation as shown in FIG. 7. In a further embodiment, the first wheel 31 is positioned as shown in FIG. 6, i.e., rearwardly, and the wheels 32 and 33 are positioned forward and may be either interior, as shown in FIG. 1, or exterior as shown in FIG. 5 to the head formation of cover 40 and such forward pair of wheels may be small as shown or exaggerated in size for effect.
